Rollup merge of #121109 - nnethercote:TyKind-Err-guar-2, r=oli-obk 
Add an ErrorGuaranteed to ast::TyKind::Err (attempt 2)

This makes it more like `hir::TyKind::Err`, and avoids a `has_errors` assertion in `LoweringContext::lower_ty_direct`.

r? ```@oli-obk```

README.md

The rustc_ast crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).

For more information about how these things work in rustc, see the rustc dev guide:
